Measuring the drug use of the residents of a city has always been difficult. In the past, current drug use was estimated from questionnaire responses, but due to the social stigma associated with drug use, a large amount of response bias was known to be present. A proposed method for measuring a city's current drug is to measure the amount of drugs detected in the inflow to the city's wastewater treatment facility. This method was used to compare the Marijuana usage, through the measurement of the active ingredient THC-COOH, of London versus Milan over a 3 week period. Samples were made at randomly chosen times throughout the day for 21 consecutive days in both cities. Units are mg/day/1,000 people. What are the two independent samples

Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find each probability

Answers

Complete question is;

Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find the probability that a randomly selected student scored less than 218.

Answer:

0.93

Step-by-step explanation:

We are given;

Mean; μ = 200

Standard deviation; σ = 12

Random value; x¯ = 218

Z-score formula is;

z = (x¯ - μ)/σ

z = (218 - 200)/12

z = 18/12

z = 1.5

From z-table, attached, probability = 0.93

A triangle has an area of 230.86 square inches. The height of the triangle is 23.8 inches. What is the length of the base of the triangle?

I'll give brainlist!! Pls help

Answers

Answer:

Length of the base of the triangle = 19.37 inch (Approx.)

Step-by-step explanation:

Given:

Area of given triangle = 230.56 square inches

Height of the triangle = 23.8 inches

Find:

Length of the base of the triangle

Computation:

Area of triangle = (1/2)(b)(h)

Area of given triangle = (1/2)(Length of the base of the triangle)(Height of the triangle)

230.56 = (1/2)(Length of the base of the triangle)(23.8)

461.12 = (Length of the base of the triangle)(23.8)

(Length of the base of the triangle)(23.8) = 461.12

Length of the base of the triangle = 19.37 inch (Approx.)

The total surface area of the block is 32.6 square inches.

Given that, Jake has a block shaped like the prism shown in a set of toys.

What the surface area of a prism?

To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.

The total surface area of a prism = (2 × Base Area) + (Base perimeter × L).

Here, area = 2 ×1/2×2×2.3 +(2+2.5+2.5)×4

= 4.6+28

= 32.6 square inches

Therefore, the total surface area of the block is 32.6 square inches.
